I'm new and complete beginner in vr, I pre-order a quest 3s, and when I get it I had a immense issue, it was blurry asf, I didn't know what to do, but while setting up the setting I saw I could adjust the lenses, and so I did it, and it help but still blurry, then I fill for a refund, later on I checked and learn about what's a pd, or imd, and measure mine and I saw it was 77, and I get my answer to why it was blurry, at moment like that I understand why the Vision Pro make people scan their face to build their headset, even tho I understand it's not simple but that'd be great if meta had a setting to make special headset for people with bigger ipd, even if we have to pay more, but that'd be. great
You may be thinking of the Big Screen Beyond, not Vision Pro. The BSB has custom made face interfaces from 3d scans of your head. It still only supports up to 74mm IPD though.
The Vision Pro supports up to 75mm.
The Quest 3s has 68 max. The Quest 3 has 70 max. However the Quest 3 lenses are very different to the Quest 3s, they aren't blurry if you look through the sides of them (there's no sweet spot). So it should handle out of range IPD better. Although I haven't tested that because my IPD is around 68-69.
As kojack says, the pancake lenses in the Quest 3 are way better at handling edge of vision clarity compared to the Quest 2 and 3s Fresnel lenses.
Aside from clarity, the other problem is eye comfort. You need the two images to be positioned where your eyes expect them to be so that you're not straining (forcing a slight squint). I find I'm pretty comfortable with an IPD setting that's maybe 1 mm either side of my eye's IPD, 2mm is very borderline, more than that and my eyes become unconfirmable after a short time, even if the image is sharp.
If your eyes are 77, I'd say it's touch and go whether you'd find even a 75mm headset ok. If you can, I'd advise to find a place to try one out to be sure.

Are you sure that this measurement was correct? 77 is not really typical distance between pupils of eyes. Try Eye Measure app, it scans your face automatically to detect the distance.
If you still have couple of weeks left for return, may I suggest you to try using it for longer? It may sound counterintuitive, but I recommend you to try it out, because I had the same experience as a first time VR user. Everything was too blurry and it was hard to read anything. But to my surprise, my eyes gradually adapted in a week or so, and now I’m able to see with much more clarity both in VR and in real life. If you wear glasses, you can buy custom optical lenses for Quest 3

The other issue is if your IPD doesn't match the headset IPD, then the VR world will be scaled wrong.
In the game engine there are effectively two cameras placed to mimic your eyes. If they are placed with the same IPD as your eyes, then everything in VR should look correctly sized. distance will feel off too if you don't have the right IPD.
This may be minor, but every little thing can cause vr sickness in someone.
The Rift-S and Go have a fixed IPD of 64mm. There's software IPD (try to fix the game engine scale), but no hardware,, the lenses can't move. As I'm about 69mm, the Rift-S never quite lined up right. If one eye was centred on its lens, the other eye was off centre and a little blurry. I'd have to move the headset around until I got a good balance. After that, I'd forget, I've spent MANY hours in the Rift-S and didn't have a problem, but it was annoying after the Rift CV1's IPD slider.
So yeah, a Quest 3 might work due to its pancake lenses. But all fresnel lens headsets (pretty much every headset) has a limited sweet spot in the centre of each lens and it less tolerant of out of range IPD.
Yeah, it may be that I've gotten used to the continuous adjustment on the Quest 3 and Pro.
Getting it just right kind of spoils you after a while, having 2mm out is quite noticeable now. I can't remember what the 3 settings on the Quest 2 equated to but maybe I was using something that was at least 2mm out without an issue back then.
Edit: just checked and it was 58, 63 and 68 so yeah, at least 2mm out for me at 65-66mm, seemed fine.
